Problems with AVIC-N2, Weird

I am installing an AVIC-N2 for a buddy of mine, along with it is the 5.1 system (models DEQ-P8000, and AXM-P8000), also installed a back-up camera and the voice guidance speaker (because the factory VG through interior speakers is disabled with 5.1)

I went through and set up the N2 for 5.1, I also set the digital input on the DEQ to use the optical cable coming from the AVIC.  I also turned on the back-up camera on the AVIC.  Ok, now heres the problems.

- 1: When I put a DVD into the unit it asks me if I want to play the DVD, I press yes, it pops up the "front seat viewing is prohibited blah blah blah" I press the ebrake, release it then press it again, warning goes away.  So the screen shows the movie is playing at the top, but all I see is a black screen.  No image!?!? Just a black screen.  I also get no signal through either the RCA's or the optical cable to the DEQ so I get no sound?!?!  It shows the elapsed time of the movie and everything and says Dolby 5.1ch, but no image, no sound? 

- 2: Another problem I am having is everytime I try to move the volume knob "Mute" appears on the screen, I press anywhere on the screen and it goes away, move the knob again and it pops right back up.

- 3: Also, with the voice gudance speaker hooked up, when I say a command it is supposed to repeat it, It confirms my command on the screen when I say it, but no sound from the VG speaker.  I've checked the volume on it and it is all the way up.

- 4: Last problem.  When I put it in reverse, the back-up camera screen pops up and says "Images may be reversed" but... NO IMAGE!?!?  I know the cam is working because when the video cord is unplugged from the AVIC brain and plugged into a simple TV I get an image. 

All of the other functions such as navigation screens and everything seems to be functioning properly.

ANYONE HAVE ANY THOUGHTS ON ANY OF THESE PROBLEMS???  Or do I just have a junk AVIC-N2???
